Description
I've been trying to download some files of off my institute's website. They use jwplayer with the
{media_id}-{player_id}.jsformat. The .js file contains the exact URL (token included) to access the required JSON metadata but youtube-dl doesn't work even if I have provided the actual tokenized version of the JSON link.Caused when using the webpage as input.
Caused by using the tokenized link to JSON.
A solution I've come up with works on all video preview page that is obtained by using any link of the format
https://cdn.jwplayer.com/players/{media_id}-{player_id}.htmlA js parser(noob's implimentation below) that extracts the
var jwConfig = {}from the script_tag and subsequently extracts the correct media_uri/playlist_uri would do the trick.The .js data(request.content) should be treated as a str/bytes object and split using the (";") delimiter. The element [-5] (please verify) should be the appropriate variable (jwConfig). Removing the
var jwConfig =(incl. spaces) then usingjson.loads()to get a dictionary. This dictionary has a playlist key which contains the JSON metadata. (might also have to replace the // with https://)Probable solution for the preview page of most media files (jwplayer-hosted/cloud-hosted)
When visiting the url returned after this, we get a JSON document similar to the ones we get when using a untokenized media.
